George Zimmerman, the man whose acquittal on murder and manslaughter charges in the fatal shooting of Trayvon Martin set off a wave of protests across the nation, helped rescue a family from an overturned SUV four days after the verdict, the Seminole County Sheriff's Office said in a statement Monday.

The statement said that on Wednesday, at approximately 5:45 p.m. ET, the sheriff's office responded to a single car accident at an intersection in the Sanford, Fla., area not far from where Zimmerman, 29, shot Trayvon, 17, in February 2012. The statement said a blue Ford Explorer had run off the road and rolled over with a family of four inside.

When a deputy arrived at the scene, two men had already helped the family out of the SUV. One of the men was Zimmerman, a former neighborhood watch coordinator in Sanford.

"Zimmerman was not a witness to the crash and left after making contact with the deputy," the statement said. "There were no report of injuries."

A jury of six women acquitted Zimmerman, who pleaded self-defense, of second-degree murder and manslaughter charges July 13. That set off protests across the nation, highlighted by "Justice for Trayvon" rallies held Saturday in more than 100 cities.
